Tonight will be the first of a two-night primetime explosion of ice dancing ... and then it will disappear for another four years.

When we last saw our ice dancing heroes, Canada's Tessa Virtue and Scott Moir where edging American hopefuls Meryl Davis and Charlie White for the gold in 2010. Four years later ... it will be the same two gunning for the gold.

In Sunday's short program, Virtue and Moir posted the best score of the day (76.33) until Davis and White took the ice as the 24 and final couple. The Michigan couple scored a world-record 78.89 points to end the day in first.

The two other U.S. couples, Madison Chock and Evan Bates and the brother-sister duo of Maia and Alex Shibutani, should also see a good amount of face time. Chock and Bates are 8th and the Shibutanis are 9th.

SUCCESS ON THE SLOPES

Silver and bronze medals in the men's Super-G will be the only Sunday U.S. medals to hang a hat and maybe some couch time on tonight.

Bode Miller, in his fifth and likely final Olympics, is a familiar face to many Olympics fans. But Andrew Weibrecht, who took silver in these games and bronze (to Miller's silver) in 2010, is a fresh face. He overcame many injuries to get to this point.
